Superheroes aren’t the only ones who mask
In ‘The Dark Knight Rises,’ Christian Bale reprises his role as Batman alongside Joseph Gordon-Levitt’s young police officer Robin John Blake. Officer Blake informs Batman that he is not afraid.
Batman explains that his mask is for the sake of those he cares about. Even if Covid isn’t talking about masks, the comparison is still there, and more foreshadowing is coming up. You’re a real superhero if you safeguard the people you care about by hiding behind a mask.
